Abstract:

Hydrogel is a kind of polymeric materials, have attracted some theoretical and experimental studies.  The new hydrogel predominately consists of MMS (macromolecular microsphere), chains and water molecules, which shapes its well-defined structure and high mechanical strength. But, how is it phase transition and forming this well-defined micro-structure? Why the hydrogels have such high mechanical strengths? What is the structure-property relationship? How do the structural factors affect, such as nanoparticle size, grafting density, polymer chain length, entanglement, and so on? Here we will review some mathematical progress to partly answer them, including phase transition, micro-structure, macro-property and related numerical methods. Meanwhile, we also present some mathematical problems to be solved.
